我想知道一个Activity是否成功启动了IntentService
.
由于可以绑定IntentService
通道bindService()
以使其保持运行,因此可能的方法是检查是否在服务对象startService(intent)
的调用onStartCommand(..)
或调用中调用结果onHandleIntent(..)
.
但是如何在活动中检查?

我目前正在Gjs上构建一个简单的应用程序,它应该改变我的gnome-shell的背景图像.gsettings
可以在此处找到使用-tool 如何完成此操作的解决方案.
由于我想围绕它构建一个桌面应用程序,我想org.gnome.desktop.background.picture-uri
通过使用Gio的GSettings
类更改-key.但是使用set_X()
-method并不会改变密钥的值.
这是我更改gsettings值的代码:
var gio = imports.gi.Gio;
// Get the GSettings-object for the background-schema:
var background = new gio.Settings({schema: "org.gnome.desktop.background"});
// Read the current Background-Image:
print( "Current Background-Image: "+background.get_string("picture-uri") );
if (background.is_writable("picture-uri")){
// Set a new Background-Image (should show up immediately):
if (background.set_string("picture-uri", "file:///path/to/some/pic.jpg")){
print("Success!");
}
else throw "Couldn't set the key!";
} else throw "The key is not writable";

读取值确实按预期工作,is_writable()

使用iOS Facebook SDK 3.0,它需要在应用程序的info.plist上定义FacebookAppID及相关的URL Scheme.我想远程定义这些(向我自己的服务器请求app id).那么2个不同的问题:
我有一个IP地址,例如char *ip = "192.168.1.13"
需要将它转换成这个"13.1.168.192"
在C中是否存在适当的可能性,或者我必须通过简单地制作令牌并将它们再次放在一起来自己做?
